STEERING DEVICE FOR. TRACTION-ENGINES.

Specification of Letters Patent.

Application filed August as, 1910.

To all whom it may concern: g

Be it known that I, THOMAS HUGHES CUDDY, of the village of Sandford, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Steering Devices for Traction-Engines, of which thefollowing is the specification.

My invention relates to a steering device for a traction engine or other such machine, and the object of the invention is to provide .a simply constructed, durable and efficient engine, the parts being arranged and constructed as hereinafter more particularly described.

Figure 1 is a side elevation of the device as it appears when in use. Fig. 2 is an enlarged detailed plan view .of the attachment showing the manner in which it is secured to the front axle of the traction engine.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 represents a traction engine of any approved form having a front axle 2 and a rear axle 3 provided with theusual carriage wheels, it being understoodthat the front axle is swung on a center pin located at 4 as is customary.

and-11 and 17 and 18 are plates fastened to the extending ends of the said beams, which plates receive the beam 19, said beam being held in a fixed position by removable bolts 20. The beam 19 carries end pieces 21 which provide bearings for bell cranks 22 and 23 carrying guiding wheels 24 and 25. I have not entered into details regarding the formation of these bearings as any approved form can be used which will allow the wheels 24 and 25 to swing at the ends of the beam.

A block 26 is secured centrally to the beam 19 and a T-bar 27 is swivelly secured to the block bymeans ofa pin 28 which pin is held at its upper end by a strap 29 passing rearwardly to the cross beam 16. Cables 30 and 31 pass from the ends of the cross piece of the T-plate backwardly to the drum 5 where they-are fastened.

32 and 33 are similar bars pivotally secured to the forward portion of the T-plate by a bolt 34; The bars have their ends connected by pins 35 with links 36 and 37 which pass to the forwardly directed arms of the bell cranks where they are fastened.

According to the above construction it is seen that the wheels 24 and 25 can be completely controlled by the cables 30 and 31 passing to the drum,which drum is directly controlled by the operator on the traction engine in the usual way. If the cable 30 be wound on the drum-feeble 31 will wind off, so that the T-arm is swung in a direction which will cause the forwardly directed arms of the bellcranks 22 and 23' to swing in a left hand direction. Consequently the front axle 2 of the engine is swung in a left hand direction.

I am aware that devices provided with guiding wheels have been constructed to turn the front axle of a traction engine, but have found that such devices are more or less impractical for the reason that the guid; ing wheel is located too far ahead of the engine with the result that it cannot turn quickly when desired. With my device the guiding wheels can be located very close to the front axle so that the engine can be turned very quickly. Further asthere are two guide wheels supplied with the attachment there is no trouble in holding it in the furrow when plows are being drawn. The bolts 20 allow the beam 19 to be moved endwise so that the distance of the engine from the furrow can be adjusted.

In order to prevent the forward end of the T plate from sagging I have supplied the strap 38 which passes from the pin 28 to a pin 39 extending from the T-plate. The action of this will readily be understood.

\Vhat I claim as my invention is:

l. The combination with the front axle of a traction engine, and a steering drum carried by the engine, of a set of forwardly extending beams swingably axle, a cross beam secured to the forward end of the latter beams, guide Wheels swivelly secured to the ends of the cross beam, a Tplate pivolally fastened to the cross beam, means connecting the T plate with the guide Wheels, and means controlled by thedrum for swinging the plate as and for the purpose specified.

2. The combination with the front axle of a traction engine, and a steering drum carried by the engine, of a set of beams swingably secured to the front axle, a cross beam secured. to the forward ends of the latter beams, bell cranks pivotally secured to the ends of the cross beam and carrying secured to the guide Wheels, a T plate pivotally secured to the cross beam, cables uniting the opposite ends of the T plate to the drum and means connecting the T plate with the bell cranks, as and for the purpose specified.

3. The combination with the front axle of a traction engine, and a steering drum carried by the engine, of a set of beams swingably secured to the front axle, a crass beam secured to the latter beams by bolts, bell cranks forming axles for a set of guide wheels, a T "plate pivotally secured to the cross beam, cables passing backwardly to the drum from the opposite ends of the T plate bars pivotally secured to the forward end of the T plate and links connecting the bars to the bell cranks, as and for the purpose specified.
